950 W AC-Input and DC-Input Power Supplies

The 950 W AC-input (PWR-950-AC) and DC-input (PWR-950-DC) power supplies can be installed in the Catalyst 6503 and Catalyst 6503-E switch chassis only. Due to form factor differences, the 950 W AC-input and DC-input power supplies cannot be installed in any other Catalyst 6500 series switch chassis.

The 950 W power supplies (see Figure A-1) do not connect directly to source AC or source DC but use Power Entry Modules (PEMs), located on the front of the Catalyst 6503 and Catalyst 6503-E switch chassis, to connect the site power source to the power supply located in the back of the chassis. The form factor is the same for the AC-input and DC-input power supplies.

The AC-input PEM (shown in Figure A-2) and DC-input PEM (shown in Figure A-3) provide an input power connection on the front of the switch chassis to connect the site power source to the power supply. You can connect the DC-input power supply to the power source with heavy gauge wiring connected to a terminal block. The actual wire gauge size is determined by local electrical codes and restrictions.

Note The system (NEBS) ground serves as the primary safety ground for Catalyst 6503 and Catalyst 6503-E chassis that are equipped with 950 W DC-input power supplies and DC-input PEMs. The DC-input power supplies for these chassis do not have a separate ground.

The PEMs have an illuminated power switch (AC-input model only), current protection, surge and EMI suppression, and filtering functions.

Description

AC-input type

Autoranging input with power factor correction (PFC)

Note Power factor correction is a standard feature on all Catalyst 6500 series AC-input power supplies. PFC reduces the reactive component in the source AC current allowing higher power factors (typically 99 percent or better) and lower harmonic current components.

AC-input voltage

•Low-line (120 VAC nominal)—90 VAC (min) to 132 VAC (max)

•High-line (230 VAC nominal)—170 VAC (min) to 264 VAC (max)

AC-input current

•12 A @ 120 VAC

•6 A @ 230 VAC

AC-input frequency

50/60 Hz (nominal)

Branch circuit requirement

Each chassis power supply should have its own dedicated, fused-branch circuit:

–Source AC can be out of phase between multiple power supplies in the same chassis, which means that PS1 can be operating from phase A and PS2 can be operating from phase B.

–For high-line operation, the power supply operates with the hot conductor wired to a source AC phase and the neutral conductor wired either to ground or to another source AC phase as long as the net input voltage is in the range of 170 to 264 VAC.

–Source AC can be out of phase between AC inputs on power supplies that are equipped with multiple AC inputs, which means that power cord 1 can be plugged into phase A and power cord 2 can be plugged into phase B.

•Off—Source AC voltage falls below 70 VAC, is not present, or the PEM is turned off.

DC-input power supplies:

•Green—Source DC voltage is OK. (-40.5 VDC or greater.)

•Off—Source DC voltage falls below -33 VDC or is not present at the PEM.

FAN OK

Green—Power supply fan is operating properly.

Off—Power supply fan failure is detected.

OUTPUT FAIL

Red—Problem with one or more of the DC-output voltages of the power supply is detected.

Off—DC-output voltages within acceptable margins.

Note For proper operation of the OUTPUT FAIL LED, systems with single power supplies must be configured with a minimum of one fan tray and one supervisor engine. Systems with dual power supplies must have a minimum configuration of one fan tray, one supervisor engine, and one additional module. Failure to meet these minimum configuration requirements can cause a false power supply output fail signal.

The 3000 W AC-input power supply (WS-CAC-3000W) is supported in the following Catalyst 6500 series switches:

•Catalyst 6506

•Catalyst 6506-E

•Catalyst 6509

•Catalyst 6509-E

•Catalyst 6509-NEB

•Catalyst 6509-NEB-A

•Catalyst 6509-V-E

•Catalyst 6513

•Catalyst 6513-E

The 3000 W power supply (see Figure A-13) shares the same form factor as the 1000 W, 1300 W, 2500 W, 4000 W, and 6000 W AC-input power supplies.

Note The 3000 W AC-input power supply needs 220 VAC to deliver 3000 W of power. When operating with 110 VAC, it delivers only 1400 W. In addition, the power supply needs 16 A, regardless of whether it is plugged into 110 VAC or 220 VAC.

Specification

Description

AC-input type

Autoranging input with power factor correction (PFC).

Note Power factor correction is a standard feature on all Catalyst 6500 series AC-input power supplies. PFC reduces the reactive component in the source AC current allowing higher power factors (typically 99 percent or better) and lower harmonic current components.

AC-input voltage

•Low-line (120 VAC nominal)—90 VAC (min) to 132 VAC (max)

•High-line (230 VAC nominal)—170 VAC (min) to 264 VAC (max)

AC-input current

•16 A @ 200 VAC (3000 W output)

•16 A @ 100 VAC (1400 W output)

AC-input frequency

50/60 Hz (nominal) (±3% for full range)

Branch circuit requirement

Each chassis power supply should have its own dedicated, fused-branch circuit:

•For North America—20 A

•For International—Circuits sized to local and national codes

•All AC power supply inputs are fully isolated.

–Source AC can be out of phase between multiple power supplies in the same chassis, which means that PS1 can be operating from phase A and PS2 can be operating from phase B.

–For high-line operation, the power supply operates with the hot conductor wired to a source AC phase and the neutral conductor wired either to ground or to another source AC phase as long as the net input voltage is in the range of 170 to 264 VAC.

–Source AC can be out of phase between AC inputs on power supplies that are equipped with multiple AC inputs, which means that power cord 1 can be plugged into phase A and power cord 2 can be plugged into phase B.

8700 W AC-Input Power Supply

Catalyst 6500 series switch support for the 8700 W AC-input (WS-CAC-8700W-E) power supply along with any power supply output restrictions are listed in Table A-37.

Note Because of the form-factor difference, when you install an 8700 W power supply in a Catalyst 6506, Catalyst 6509, or Catalyst 6509-NEB chassis you must relocate the system ground connection from the chassis ground pad connection to the two system ground studs located on the 8700 W power supply faceplate. Installing an 8700 W power supply in the other Catalyst 6500 series chassis does not require that you move the chassis system ground connection to the power supply.

The 8700 W power supply cannot be installed in the Catalyst 6503, Catalyst 6503-E, and Catalyst 6504-E switch chassis.

8700 W Power Supply Specifications

Table A-38 lists the specifications for the 8700 W AC-input power supply.

Table A-38 8700 W AC-Input Power Supply Specifications

Specification

Description

AC-input type

3 AC-inputs per power supply. High-line input with power factor correction (PFC) included.

Note Power factor correction is a standard feature on all Catalyst 6500 series AC-input power supplies. PFC reduces the reactive component in the source AC current allowing higher power factors (typically 99 percent or better) and lower harmonic current components.

AC-input voltage

(One-phase)

•Low-line (120 VAC nominal)—90 VAC (min) to 132 VAC (max)

•High-line (230 VAC nominal)—170 VAC (min) to 264 VAC (max)

AC-input current

16 A each input

AC-input frequency

50/60 Hz (nominal) (±3% for full range)

Branch circuit requirement

Each power supply input should have its own dedicated, fused-branch circuit:

•For North America—20 A

•For International—Circuits should be sized according to local and national codes

•All AC power supply inputs are fully isolated. This means that source AC can be out of phase between multiple AC inputs on the same power supply or different AC power supplies that are installed in the same chassis. For the 8700 W power supply, this means that power cord 1 can be plugged into phases A-B, power cord 2 can be plugged into phases B-C, and power cord 3 can be plugged into phases C-A, A-B, or B-C.

Power supply output capacity

The power supply output capacity is dependent on the number of AC power cords (1, 2, or 3) attached and the source AC voltage (110 VAC [low-line] or 220 VAC [high-line]) applied to the power supply inputs.

The 8700 W AC-input power supply is limited to reduced wattage ratings when it is installed in the following Catalyst 6500 series chassis:

•4000 W maximum output when it is installed in a Catalyst 6506, Catalyst 6509, or Catalyst 6509-NEB switch chassis.

•4500 W maximum output when it is installed in the Catalyst 6509-NEB-A switch chassis.

•6000 W maximum output when it is installed in the Catalyst 6513 switch chassis.

Note The power supply will not power up if you attach only one power cord and the power cord is connected to low-line (110 VAC nominal) source AC.

2800 W operation

2800 W maximum with the following combinations of power cords and source AC voltage applied to the power supply inputs:

•Two AC inputs are connected to low-line (110 VAC nominal); the third AC input is not connected.

•One AC input is connected to low-line (110 VAC nominal); one AC input is connected to high-line (220 VAC nominal); the third AC input is not connected.

•One AC input is connected to high-line (220 VAC nominal); two AC inputs are not connected.

4200 W operation

4200 W maximum with the following combinations of power cords and source AC voltage applied to the power supply inputs:

•Off—Source AC voltage falls below 70 VAC, is not present, or the power supply is turned off.

220VAC 1, 2, and 3

•Green—High-line AC is present on the respective AC inputs. (Input voltage is 170 VAC or higher.)

•Off—Source AC voltage falls below 170 VAC (running at low-line voltage), is not present, or the power supply is turned off.

FAN OK

•Green—Power supply fan is operating properly.

•Off—Power supply fan failure is detected.

OUTPUT FAIL

•Red—One or more of the power supply DC-output voltages is out of the normal operating range:

–For +3.3 VDC output: 2.7-3.0 VDC (min); 3.6-3.8 VDC (max)

–For +12 VDC output: 10.5-11.5 VDC (min); 12.6-13.0 VDC (max)

–For +42 VDC output: 38.0-40.0 VDC (min); 45.0-52.0 VDC (max)

•Off—All DC-output voltages are within normal operating ranges.

Note For proper operation of the OUTPUT FAIL LED, systems with single power supplies must be configured with a minimum of one fan tray and one supervisor engine. Systems with dual power supplies must have a minimum configuration of one fan tray, one supervisor engine, and one additional module. Failure to meet these minimum configuration requirements can cause a false power supply output fail signal.

Remote Power Cycling Feature

The 8700 W power supply is equipped with a remote power cycling feature that allows you to remotely turn on or turn off the power supply through an external relay controller box. Figure A-19 shows a typical remote power on/off setup. A three-position terminal block and a switch, located on the lower right quadrant of the power supply faceplate (see Figure A-18), provide the interface to the external relay controller box.

Figure A-19 Remote Power On/Off Feature Components

Terminal Block

The terminal block has three contacts labeled 1, 2, and 3. Two control wires from an external relay controller box attach to either positions 1 and 2 or positions 2 and 3. Positions 1 and 2 are used when the relay controller box contains a normally-open (NO) type of relay. Positions 2 and 3 are used when the relay controller box contains a normally-closed (NC) type of relay.

Relay Controller Box Switch

The relay controller box switch, located next to the terminal block, allows you to match the power supply power control signal's active state with the type of relay contained in the external relay controller box (either a normally-open type of relay or a normally-closed type of relay).

Ferrite Bead

A plastic bag containing one ferrite bead and two 4-inch plastic ties is included with the 8700 W power supply AC power cords. The ferrite bead is a passive device that limits high-frequency interference on interface and control cables, and is only required when you install the remote power-cycling feature that is supported by the 8700 Watt power supply. The ferrite bead is installed on the two control wires that come from the relay controller box to the terminal block on the 8700 W power supply. The ferrite bead should be installed as close as possible to the power supply terminal block for the bead to be effective. You do not need the ferrite bead for 8700 Watt power supply installations that do not include the remote power-cycling feature. If you need to install the ferrite bead, refer to "Installing the Ferrite Bead" procedure.

Remote Power-Cycling Operation

This feature allows you to remotely power cycle the Catalyst 6500 series switch using any appropriate third-party relay controller. This eliminates the need for you to have access to the supervisor engine console or CLI to control power cycling. Table A-40 lists the relay controller box relay type, the corresponding power supply terminal block positions, and a description of the power-cycling operation.

1When operating with 100-120 VAC, you must use two or three AC power cords and the power supply output is limited to either 2800 W (2 inputs) or 4200 W (3 inputs).

2The PDU power cable is designed for users who power their switch from a PDU. The end of the cable that plugs into the chassis power supply has a C19 connector; the other end of the cable that connects to the PDU has a C20 connector.

Power Supply Redundancy

Catalyst 6500 series switching modules have different power requirements. Depending upon the wattage of the power supply, certain switch configurations might require more power than a single power supply can provide. Although the power management feature allows you to supply power to all installed modules with two power supplies, redundancy is not supported in this configuration. Redundant and combined power configurations are summarized in Table A-42. The effects of changing the power supply configurations are summarized in Table A-43.

Note For proper load-sharing operation in a redundant power supply configuration, you must install two modules in the chassis. If you fail to install two modules, you might receive spurious OUTPUT FAIL indications on the power supply.

Note In systems that have two different sized power supplies installed, you may not have true redundancy. If the larger wattage power supply fails, the smaller wattage power supply might not be able to handle the entire load by itself.

Table A-42 Power Supply Redundancy

If you have two power supplies of

and redundancy is

Then

Equal wattage

Enabled

The total power drawn from both supplies is never greater than the capability of one supply. If one supply malfunctions, the other supply can take over the entire system load. Each power supply provides approximately half of the required power to the system. Load sharing and redundancy are enabled automatically; no software configuration is required.

Unequal wattage

Enabled

Both power supplies initially come online. For the Catalyst operating system, if the difference between the two power supply's output wattage is less than 10 percent of the higher output wattage power supply, redundancy is enabled. If the difference is greater than 10 percent, the lesser wattage power supply is disabled.

For Cisco IOS, both power supplies come on. The total available wattage is the output wattage of the higher wattage power supply.

Equal or unequal wattage

Disabled

The total power available to the system is approximately 167 percent of the lower-wattage power supply. The system powers up as many modules as the combined capacity allows. If the higher-wattage power supply fails, the lower-wattage supply might also shut down due to overcurrent protection to prevent damage to the lower-wattage power supply.

Table A-43 Effects of Power Supply Configuration Changes

Configuration Change

Effect

Redundant to combined

•System log and syslog messages are generated.

•System power is increased to approximately 167 percent of the lower-wattage power supply.

•The modules marked as power-deny in the show module Status field are powered up if there is sufficient power.

Combined to redundant

•System log and syslog messages are generated.

•System power is the power capability of the higher-wattage supply.

•If there is not enough power for all previously powered-up modules, some modules are powered down and marked as power-deny in the show module Status field.

Equal wattage power supply is inserted with redundancy enabled

•System log and syslog messages are generated.

•System power equals the power capability of one supply. (Both supplies provide approximately one half of the total current.)

•No change in the module status because the power capability is unchanged.

Equal wattage power supply is inserted with redundancy disabled

•System log and syslog messages are generated.

•System power is the combined power capability of both supplies.

•The modules marked as power-deny in the show module Status field are brought up if there is sufficient power.

Higher wattage power supply is inserted with redundancy enabled

•System log and syslog messages are generated.

•The system disables the lower-wattage power supply; the higher-wattage supply powers the system (Catalyst operating system).

•For Cisco IOS, both power supplies come on. The total available wattage is the output wattage of the higher wattage power supply.

Lower wattage power supply is inserted with redundancy enabled

•System log and syslog messages are generated.

•The system disables the lower-wattage power supply; the higher-wattage supply powers the system (Catalyst operating system).

•For Cisco IOS, both power supplies come on. The total available wattage is the output wattage of the higher wattage power supply.

Higher or lower wattage power supply is inserted with redundancy disabled

•System log and syslog messages are generated.

•System power is increased to the combined power capability of both supplies.

•The modules marked as power-deny in the show module Status field are brought up if there is sufficient power.

Power supply is removed with redundancy enabled

•System log and syslog messages are generated.

•If the power supplies are of equal wattage, there is no change in the module status because the power capability is unchanged.

If the power supplies are of unequal wattage and the lower-wattage supply is removed, there is no change in the module status.

If the power supplies are of unequal wattage and the higher-wattage supply is removed, the lower-wattage power supply must be turned on manually. (The system had previously turned off the lower-wattage power supply.)

Power supply is removed with redundancy disabled

•System log and syslog messages are generated.

•System power is decreased to the power capability of one supply.

•If there is not enough power for all previously powered-up modules, some modules are powered down and marked as power-deny in the show module Status field.

System is booted with power supplies of different wattage installed and redundancy enabled

•System log and syslog messages are generated.

•The lower-wattage supply is disabled (Catalyst operating system).

•For Cisco IOS, both power supplies come on. The total available wattage is the output wattage of the higher wattage power supply.

System is booted with power supplies of equal or different wattage installed and redundancy disabled

•System log and syslog messages are generated.

•System power equals the combined power capability of both supplies.

•The system powers up as many modules as the combined capacity allows.

When running redundant 4000 W, 6000 W, or 8700 W power supplies in Catalyst 6506 and Catalyst 6509 non-E series systems, if you remove the power supply in bay 1, the total system power will be reduced to 2940 W (70 A at 42 VDC) after 180 seconds (3 minutes). You can avoid this reduction in the total system power by leaving the power supply in bay 1, even in a powered down state.

If the total system power usage is greater than 2940 W, the following scenario will apply if a 4000 W, 6000 W, or a 8700 W power supply is removed from bay 1 (these scenarios are specific to only these three power supplies running in redundant mode in either the Catalyst 6506 or Catalyst 6509 non-E series systems).

•If the power supplies in bay 1 and bay 2 are running in redundant mode, the total system power will be 4000 W.

•If power supply 1 is running and you power off or remove power supply 2, the total system power will be 4000 W. The system will issue a normal power supply 2 down/remove indication warning.

•If you power down power supply 1 while power supply 2 is operating, the system will issue a normal power supply 1 down indication warning with another warning asking the user not to remove power supply 1. If power supply 1 is left in the system, even if it is powered off, the total system power will be 4000 W.

•If you remove power supply 1 from the system, a major alarm will be issued to warn that the total system power will be reduced to 2940 W and that any modules or PoE devices that cause the system to exceed 2940 W will power down in 180 seconds (3 minutes). If you insert a replacement power supply 1 in the 180-second timeframe, no action will be taken.

Note In systems that are equipped with two power supplies, if one power supply fails and the other power supply cannot fully power all of the installed modules, system power management will shut down devices in the following order:

•Power over Ethernet (PoE) devices— The system will power down PoE devices in descending order, starting with the highest numbered port on the module in the highest numbered slot.

•Modules—If additional power savings are needed, the system will power down modules in descending order, starting with the highest numbered slot. Slots containing supervisor engines or Switch Fabric Modules are bypassed and are not powered down.

This shut down order is fixed and cannot be changed.

You can change the configuration of the power supplies to redundant or combined at any time. If you switch from a redundant to a combined configuration, both power supplies are enabled (even a power supply that was disabled because it was of a lower wattage than the other power supply). If you change from a combined to a redundant configuration, both power supplies are initially enabled, and if they are of the same wattage, they remain enabled. If they are of different wattage, a syslog message displays and the lower wattage supply is disabled.
